Quantum-enhanced Large Language Models on Quantum Hardware via Cayley Unitary Adapters

Borja Aizpurua, Sukhbinder Singh, Augustine Kshetrimayum +2

Large language models (LLMs) have transformed artificial intelligence, yet classical architectures impose a fundamental constraint: every trainable parameter demands classical memo…
